Abstract

Étant donné que le nombre de couches transmises peut varier dynamiquement, le nombre de signaux de référence de démodulation (DM-RS) émis peut également varier. Cependant, étant donné que le nœud de réseau peut connaître le nombre de ports, de couches transmises ou le rang, le nœud de réseau peut utiliser le nombre en tant que partie des informations de planification par l'intermédiaire d'un canal de commande de liaison descendante ou de liaison montante. Ainsi, la génération de séquence DMRS peut être modifiée de telle sorte qu'elle dépende du nombre de ports, de couches transmises ou du rang, ce qui permet de générer une séquence aléatoire différente pour différents ports.
